How to use S12Z to measure motor phase voltage？

[jiangfeng]

Dear support:

I use the S12Z to drive the motor and try to detect the phase voltage, Is the pin(HS0 HS1 HS2) used to detect the phase voltageA,B,C?

Is the phase voltage described above correspond to Ua,Ub,Uc in the following figure? Thanks very much.
